(-b+45) is not an equation. It poses no question, and there's nothing there to solve.
If you had told us a number that results from (-b+45), then we would have been
tantalized with the question of finding the value of 'b' .
The answer is 20+25=45
If a solution containing A+ ions and a solution containing B- ions have just been mixed and [A+][B-] is greater thanKsp of AB, _____.
a= 2, b = 3 (or vice-versa)
x = -6
There is no equation in the question, only an expression. An expression cannot have a solution.
Without any equality and not knowing the plus or minus values of 1 and 45 it is not an equation so therefore it has no solution.
A + 10 = 55If you mean the solution for A, A = 45.
-6x+9 = 45 -6x = 45-9 -6x = 36 x = -6
7x+17 = 45 7x = 45-17 7x = 28 x = 4
-45 plus 512 plus 45 plus 56 = 568
The second equation is not complete and there is not sufficient information for a solution. It would make no sense for me to guess what a + b equals since, in that case, I may as well start posting my own questions and answering them!
Solution A is highly concentrated than solution B.
